What happens *after* enemy release? In a new paper, we present 7 years of infection & immune trait dynamics in 16 lake populations of stickleback. www.journals.uchicago.edu/doi/10.1086/... This is definitely the longest-scale study I've done in my career, I'm very excited to see it out. 1/6

What is the deep sea “big flat eye” fitness peak all about?

After disappearing from the Milwaukee River in the early 20th century due to overfishing and habitat loss, the new discovery of an adult sturgeon 20 miles upstream from Lake Michigan is a milestone in a massive restoration project that’s been underway for 20 years www.wuwm.com/lake-sturgeo...

“We’ve lost out on the ability to continue to improve this work to make it more effective, and to explore how to apply it to other areas…There are a lot of different ways that genetics has been used to justify prejudice and…that human-made social categories interface with biological categories“🧪

Continental-scale evidence that emergent aquatic insects sustain riparian birds, thus freshwater conservation offers considerable co-benefits to terrestrial ecosystems! A fun collaboration w/ postdoc @cschuerings.bsky.social @uwsafs.bsky.social @uwenvironment.bsky.social doi.org/10.1038/s415...

The NIH can do great stuff when we give it money

The Academy of Natural Sciences ( @acadnatsci), the oldest & 1st nat. hist. museum in North America, is under threat! Sign petition at bit.ly/save-academy to tell president of @drexeluniv to fund one of the most important educational & research institutions in the world! @geosociety.bsky.social

And furthermore, The Hoover Institution must be destroyed.

Hey faculty search committees, please standardize your job applications and be more clear about what you want. The process of customizing dozens of applications to suit slightly different requirements makes it more likely you're reading AI generated research and teaching statements. #academicsky

“What do you call your act?” “Permitting reform!”

Some interesting hidden policy tradeoffs here between infrastructure costs, safety, and environmental damage. When I was in Iceland, I was required to have studded tires through the winter because roads in most of the country aren’t salted despite the harsh winters./

This is a good article about an issue that is immensely frustrating. After recently talking briefly about trout stocking with someone who works in the PA statehouse, I can say that many legislators are really not aware of this problem.

meaningful evolution can happen fast

Turns out those Chinook salmon that finally showed up in the Upper Klamath last year were doing more than just posing for photos. 🐟🧪🌎 www.opb.org/article/2026...

A beautiful day for some great dog watching at #nokings in Bethlehem PA

Canada just released a National Freshwater Science Agenda — 10-year priorities, 800+ contributors, including Indigenous experts & knowledge holders. A good first step. Now we just need the political will to fund it. 🧪🐟🦤 www.canada.ca/en/environme...

Producing corn to make alcohol to add to gas is an extraordinarily poor use of land, and promoting it is a bad policy. Amy Klobuchar is also smart enough to know it’s bad policy, though she apparently thinks the rest of us aren’t.

Big frog today. Weirdly unconcerned about my dog.

@people.com this is excellent news, thank you for reporting it. In the future, please link to the studies you are referring to so it is easier to help people find more details. This also helps the authors see the impact of their work.

Canada's federal government is cutting in... everything: -Environment and Climate Change: They plan to cut 1400 jobs. -Fisheries and Oceans Canada: They plan to cut 767 posts of a total workforce of 8,198. -National Research Council of Canada: 196 unionized positions -... Go read the full post!

New paper from the Hendry & Barrett labs, led by Sarah Sanderson, found that after a severe drought an at-risk population of unarmoured stickleback became mostly armoured, providing insight into how extreme events can influence unique populations. onlinelibrary.wiley.com/doi/full/10....

Stickleback people, please note the updated deadline for this special collection! You have two extra months to finish your manuscripts 🥳

Not a proper #sundayfishsketch but I painted some ice fishing huts I saw in maine a couple weeks ago

It’s a big problem that the way you get endorsements is by not having your own thoughts

Some very cool environmental improvements being introduced at one of my local parks, but @pafishandboat.bsky.social ‘s designation of this brown trout population as “wild” seems to have confused the city into thinking it is native.

Yeah, Baseball! [Also give this camera guy an Oscar]

When I say things like "libertarian Abundance is a idea cooked up by people in cities who don't understand or care about anyone else's needs or interests and is a political dead-end", this is exactly the kind of guy I am talking about. I grew up in Bethlehem, PA, ~90 minutes from Philly

Out now in Contributions from me and @gilespalaeo.bsky.social, a deep dive into an early member of the sturgeon and paddlefish lineage. Bear with me, but there’s a long backstory highlighting uncertainty about the anatomy of living species and how well-studied fossils can still yield new insights.

I’ll start to regularly post photos of Lebanese fossils alongside links to charities supporting the thousands displaced in this war. Even the smallest donations can save lives Fossils on display at Memory of Time, Jbeil, and you can donate here: gofund.me/24a3cee49

The author of this piece works in what was, 150 years ago, a vast chestnut forest stretching continuously from Mississippi to Maine that has been obliterated by invasive species.

@springernature.com, if you don't ditch Straive, I won't be submitting to your journals again unless I don't have any choice in the matter. Easily the worst post-acceptance experience I've had with a paper.

it is really bad how many people across the political spectrum on social media seem to discuss things in terms of discredited genetic pseudoscience when it comes to identity

Buddha's Hand Citron. I don't think I have ever actually tasted it, but how would I know? It would have had to be just zest because this thing is all rind. No flesh, no seeds, just rind. Also, aesthetically displeasing.

old journal articles really are incredible. No standardization of style, just a bunch of eccentric weirdos writing about the stuff they were doing in the hopes somebody could make sense of it. Here's the opening of this unhinged spider article, and the next one, which is basically a prose poem.

Can confirm. The robots aren't telling me how to de-blur my figures that were sent as nice crisp pdfs
